When considering to backup your All Orders database you must be very careful in that some offline backup utilities used for System Backups may not backup the AO database. Depending on which utility you are using for system backups, you must check if the database was backed up and has a size greater than zero. If the size of the database file is zero then the backup did not work and this is because the utility did not know how to detach and reattach the database automatically.
In order to prevent costly losses in this regard, you should do a backup daily from within the AO program itself and then do your system backup. Alternatevely, you can backup your AO database from Sql Server Studio Express and then backup your system. However, backing up your system without backing up AO from within the program or the studio, again, may fail!!!!!!!!
